To li Q fiom @may concern;

Known that l, @Hennes Bananen,

i of the 'United States of America, residing at Detroit, in the county of Wayne ard Ftate of Michigan, have invented certairrneiv and u eful .improvements in lnil--Qombustion "Engines, oi -which' the relieving citize a specication, reference being had therein totheacconlpanying drawings.v

This invention relates to internal combus' tion engines, such as may be advantageously used in connection with automobiles, motor. boats, aero-planes, and various types of vehicles, and more particularly to a novel valvular arrangement by which the eiiiciency of suon engine may be materially increased,

ltiy invention aims to obviate the necessity of using cani shaft, tappet valves and their appurtenant parts, by substituting therefor rotary valves common toall of the cylinders of an engine for accurately con,

trolling the intake and exhaust ofthe cylinders.

My invention 'urther ail'ns to furnish an explosive engine 'with rotary valves, and a novel train of gears for operating the valves in timed relation to the cycle of theV engine. My invention further aims to provide an parts are assembled with a vievv of reducing the cost of manufacture and at the same tirne retain the features by which safety, durability and simplicity of vconstruction are secured, and with such ends in view, my invention resides in the novel construction to be hereinafter specifically described and then claimedD l Reference will nor/v be had to 'mi reinwd Figure l of an internal combustion enr e ance with this invention.; i

struction and arrangement of parts shown.

The following description is therefore to be broadly construed as including substitute constructions .and arrangements of parts which are the obvious equivalent of those to be hereinafter referred to. ln the drawinfg, l denotes a crank case having cylinders 2 en bloc provided with water jackets 3.

i denotes a crank shaft journaled in bearings 5 in the crank case, said crank shaft are connecting rods (i of pistons 7 operable in the cylinders 2.' The elements ,thus far described are of the conventional forni common to niany types oi explosive engines.

My invention resides in providing the' upper ends of the cylinders 2 with longitudinal tapering valve bodies `S inclosed by water jackets 9 communicating with the l Water jackets The valve bodies 8 have the longitudinal axes thereof. parallel and ,at opposite sides 'of the longitudinal axes spark plug connections, l0 in the vertical axes of said cylinders, as best shown in Fig,

.and connected to said cylinders having A '2. Thevl tapering Valve bodies 8 have the i large ends thereof open for connection mtli intake and exhaust pipes (not slloivn), and yintermediate the 'ends of said valve odio-s there are a plurality of intake and exhan connections l1 with the upper ends oi t .e cylinders 2, said intake and exhaust c nections being 'necessarily angularly d.

posedl to establish communication between i' the cylinders and the odset valve body.

Rotatable in the valve bodies-8 are taperving hollow valves 12 provided with spacedradial portsrl adapted to successively' cornvmunicate with the intake and'eirlianst c nections 11 of the cylinders 2 to supply 'cylinders with an explosive mixture and en'N -haust spent gases therefrom. The eine and arrangement of the ports i3 is suchi that the intakev and exhaust of the cylinders 'vri-lltalre place invtimed relation and in proper order corresponding to the firing of the cylu tapering ro tary valves 12 are opent@ communicate with the intake and exhaust connections and inner ends of said valve are reduced er stepped as at le, l5 and 16, to permit of a valve actuating mechanism being installed to properly rotete the valves 1% Tee re'- duced portions 14s of the valves extend into bearings 1'? of the valve bodies @and the reduced portions l5 are provided with feat-ers or keys 18 for small gear Wheels 19 adapted for rotative continuity with the valves i2. The small gear Wheels 19 are slidably retained upon the reduced portions 3.5 of the valves, by coiled compression springs 20 encircling the reduced portions 16 ot' the valves, bet-Ween the Small gear wheels 19 and caps or cups 21 mounted upon the reduced portions 16 of the valves.

meshing with the small gear Wheels 19 is a gear wheel 22 forming part of a train of gears adapted to impart movement to the valves 12 `from the crank shaft 4t of the enleine. Associated -With thev gear Wheel 22 are other gear wheels 23, 24 and 25. The gear wheels 22, 23 and 24 are revoluble on stub shafts 26 carried by the end of the en-` gine and the gear `wheel 25 is mounted on a protruding end of the crank shaft 4c. All.

oi: the gear Wheels are proportioned to rotate the valves l2 in synclironism and timed relation to properly supply and exhaust the cylinders' of the engine.

llt is tliougliiv that the operation and utility of the valvcsand the operating mech-` anisinthereot ivi-,il loe apparent Without furtlicr dscripiion, but I desire toicall particular attention to the simplicity ofconstruction, as the valve and the operating mechanism Athereof consists of comparatively ieiv parte that are easy to maintain in anoper'able condition, thus avoiding any complications in connection with the engine.,

These same valves and the operating mecha* nism thereof are applicable to pumps, coinpressors and other apparatus Where it is need-aas desired to aotomaticail control a oinraiitv .V .n u

' of ports tapering; portions of Tifi/*hat li, solai-ni is The combination with an explosive engine having cylinders, a crank sharia pistons in said cylinders between said piston and said crank shaft, of tapering, valve bodies common to all oit said cylinders and disposed in paralleiisni at opposite sides of the vertical axes ci sai-d cylinders, said valve bodies leaving open ends adapted for connection with intake and exhaust pipes, hollow ported tapering rotary valves in said valve bodies having reduced ends protruding tlierefroin,' the Y said valves being oi less length than the taperine portions of said valve bodies, angularly disposed connections between tbejupper ends of said cylinders and said valve bodies adapted to establish communication between said cylinders and said valves, gear wheeis keyed on tlie reduced ends of said valves against the ends of said valve bodies, means on the reduced ends of said valves enteriorly of said valvebodies maintaining Said gear Wheels against said valve bodies and said valves seated in. said valve bodies, and a train of `gears driven by said crank slia'ft and adapted to impart movement to the gears of said valves to rotate said valves and supply and exhaust said cylinders in timed relation to the firing thereof.
